Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an infusion port dressing. Background Technology

[0002] Currently, the infusion port dressings used in clinical practice are generally made of single-layer polyurethane (PU) membrane material. Although this material has a certain degree of breathability, allowing air and water vapor to pass through the membrane, it also has the function of blocking the invasion of microorganisms such as viruses and bacteria.

[0003] However, in actual clinical applications, existing dressings adhere completely to the patient's skin surface (e.g., Figure 5 The lack of effective ventilation between the dressing and the skin restricts the skin's pores' ability to breathe. Although the PU film is permeable to water vapor, when the ambient temperature rises or the patient sweats, water vapor that is not expelled in time will still accumulate on the skin surface, creating a localized high-humidity environment. This persistently moist state can easily lead to overhydration of the stratum corneum, causing adverse reactions such as contact dermatitis and itching. This not only forces medical staff to replace the dressing earlier (the usual 72-hour usage cycle may be shortened to 24-48 hours), increasing medical costs, but also directly affects the patient's treatment comfort. Utility Model Content

[0004] The purpose of this invention is to provide an infusion port dressing that solves the aforementioned problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An infusion port dressing includes a fixing patch and a breathable membrane. The fixing patch includes a wire mesh and an adhesive ring. The wire mesh is distributed in the middle of the adhesive ring, and the breathable membrane covered with the wire mesh is provided on the upper part of the adhesive ring.

[0007] The beneficial effects of this invention are: it can form an effective breathable gap between skin layers, allowing the skin pores to breathe without restriction, avoiding the formation of a local high-humidity environment on the skin, which could lead to adverse reactions such as contact dermatitis and itching in patients, thus improving treatment comfort; at the same time, it allows the patch to reach its normal usage cycle without the need for premature replacement, reducing medical costs.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes an activated carbon adsorption ring, and a placement groove is provided inside the rubber ring and located at the lower part of the breathable membrane, and the activated carbon adsorption ring is filled in the placement groove.

[0010] The breathable membrane is a PU membrane.

[0011] The further beneficial effects of adopting the above-mentioned method are: the activated carbon adsorption ring can adsorb some water vapor, further preventing the formation of a localized high-humidity environment on the skin. Using the existing PU film material for infusion port dressings reduces research and development costs and production costs. Attached Figure Description

[0017] The attached diagram lists the components represented by each number as follows:

[0018] 1. Fixing sticker; 11. Screen mesh; 12. Adhesive ring; 121. Placement groove; 13. Activated carbon adsorption ring; 2. Breathable membrane; 21. Positioning ring; 22. Positioning cross; 3. Release paper protective layer. Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, an infusion port dressing includes a fixing patch 1 and a breathable membrane 2. The fixing patch 1 includes a wire mesh 11 and an adhesive ring 12. The wire mesh 11 is arranged in the middle of the adhesive ring 12, and the breathable membrane 2 covering the wire mesh 11 is provided on the upper part of the adhesive ring 12.

[0022] In use, the adhesive ring 12 is attached to the periphery of the infusion port so that the mesh and breathable membrane 2 cover the infusion port. The mesh 11 fixes the infusion port, and the breathable membrane 2 blocks external bacteria and viruses from infecting the puncture site. Due to the barrier of the mesh 1, the breathable membrane 2 can form an effective air gap between the skin, so that the skin pores can breathe without restriction, avoiding the formation of a local high-humidity environment on the skin, which may lead to adverse reactions such as contact dermatitis and itching in patients, thus improving treatment comfort. At the same time, it allows the dressing to reach the normal usage cycle without the need for premature replacement, reducing medical costs.

[0023] Example 2

[0024] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0025] It also includes activated carbon adsorption rings 13, and a placement groove 121 is provided inside the rubber ring 12 and located at the lower part of the breathable membrane 2, with the activated carbon adsorption rings 13 filling the placement groove 121. The activated carbon adsorption rings 13 can adsorb some water vapor, further preventing the formation of a localized high-humidity environment on the skin.

[0026] The breathable membrane 2 is a PU membrane. It utilizes the PU membrane material currently used in infusion port dressings, reducing R&D and production costs.

[0027] Example 3

[0028] like Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0029] A positioning ring 21 is drawn in the middle of the breathable membrane 2; a positioning cross 22 is drawn in the center of the positioning ring 21. The dressing needs to be applied with the puncture point of the patient's infusion port as the center. The positioning ring 21 can help medical staff to quickly locate the dressing; the positioning cross 22 can further help medical staff to accurately locate the dressing position.

[0030] The mesh 11 is made of silk fiber; each unit of the mesh 11 is a regular hexagon. Silk fiber is soft and antibacterial, making it suitable as a material for the mesh 11. Each unit is a regular hexagon, resulting in high density and requiring less material.

[0031] A release paper protective layer 3 is provided at the bottom of the screen 11 and the adhesive ring 12. This layer is removed before application to prevent bacterial contamination during storage.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
